The biggest issue here I don't think is the malware tag, but the ad fraud accusation.
Even thought as somebody pointed out the page linked can be biased, based only on what they state and the emails from Google, this is another case of David Against (automated) Goliath.
From my point of view this is just another drop in the pound of what is already being built as a case against Google (and also Apple) for monopoly.
P.S.: I've used Droidscript in the past, and I do think it's too powerful an app that can be abused. But that happens to a lot of things in life, right?
